' To all whom it may concern:

Be it known that I, WILLIAM C. Tanoon- ING, a citizen of the United States, residin at 'Hackensack, New Jersey, have invente certain new and useful Im rovements in Terminal-Connectors, of whic the following is a clear, full, and exact description.

The object of this invention 1s to provide an improved connector terminal for making battery or other electrical connections, which will be simple and cheap to make, readily applied and will of itself secure a good electrical connection.

In 'carryin out the invention I provide members res' 'ently movable away from each other at their outer ends and joined at their inner ends. I provide a means which normall tends to hold the outer ends apart, whic I prefer to have consist of the sprin quality of the material of which the termina is ma e. The terminal is usually formed of wire, in which case the spring is secured by a convolution of the wire itself. 'The conductor may be secured to either member of the terminal connector in any desired manner, as by winding or soldering.

At the free ends of the members I locate loops so situated that they are in the same plane of movement as the members themselves, so that when the members are comressed the loops may overlie each other and e slipped over the terminal post or screw, that is to receive them. When so slipped over a post or terminal and released, the s ring 0 the connector will tend to separate t e two members and thus cause each of them to strongly grip opposite sides of the terminal.

When the loops are formed of sheet metal, I prefer to corru ate or screw thread them that they may ta e hold of a shank of a terminal screw of. ordinary st le, in which case I also prefer to have the 00 s of suflicient de th to form sleeves or cylind a etter surface contact. wire the loops, instead of being of but one convolution, may be of a number with the successive loops closed on each other, in

which case the spiral itself will in good man-.

nector showing the preferred form; Fig. 2 is a side elevation of Fig. 1 Fig. 3 is a plan view ers so as to get When made of of the terminal connector of Figs. 1 and 2 with the loops closed upon 0 ch other for insertion on a post; Fig. 4 1s a p an view of a modified connector in'closed position; Fig. 5 iso side elevation of the terminal of Fig. 4; F' 6 is a plan of a still further modification, an Fig. 7 1s a slde elevation of'Fig. 6 with one of the sleeves in section.

As shown in Figs. 1, 2 and 3, the terminal connector consists of one piece of wire having two stralght members 1, 1, each terminating in a sleeve 2 of closed loops of the wire, each loop being oppositely turned so that a continuous sleeve with a substantially threaded interior will be provided with the threads, preferably all running one way.

The'two members 1 are joined at their inner end'by a s ring loop 3 which tends always to olppn t em out into the os ition of Fig. 1. e conductor 4 may e passed through the spring loop 3 and wound or soldered on one of the members as shown.

In the. construction of Figs. 4 and 5 the terminal connector is; shown as formed of two sheet metal spring members 11. The members have sleeves 12 at their outer ends and each member is of half the entire width of the blank from which it is formed, while the hinge'14 is of the entire width of such blank. The object of this will at once be obvious by reference to Fig. 5 where the parts are shown p in position on a threaded post or screw. A hole 15 in the hinge '14 and a smaller opening 16 may be provided for the conductor.

As shown in Figs. 6 and 7 the two members 21 and 21 and the spring loop 23 are similar to my preferred form, but the sleeves or 100 s 22, 22 are sheet metal stam ings with t readed interiors and with tubular edges 24 to grasp the members 21, 21. It is obvious that these threaded sleeves of sheet metal are just as serviceable, with the construction of Figs. 4 and 5 as with that just described.

Though I have shown two different species of terminal construction herein and resented claims generic to both species an others specific to the coiled wire construction, I do another application and patent for that species unclaimed specifically in this case.

What I claim is: 1. A terminal connector com rising two members joined together and res' iently movable away from each other inplanes substan- I wire members joined with a spiral thereof,

tially parallel, the free ends of said members having openings lying in a plane parallel to the plane of movement of said members.

2. A terminal connector comprising two members joined together and each carrying at its free end a sleeve having its axis at right angles to the plane of movement of the members, and resilient means adapted to 'hold said members away from each other.

3. A terminal connector comprising two wire members joined with a splral thereof, the free ends of each member being bent into a loop, having its axis at right anglesto the plane of movement of the members.

4. A terminal connector comprising two wire members joined with a spiral thereof, the free ends of each member being bent into loops of a spiral with the convolutions closed 313011 each other to form corrugated cyliners.

5. A terminal connector comprising two the free ends of each member bein bent into loops of a spiral with the convolutions closed upon each other to form corrugated cylinders, said members being adjacent each other and the cylinders extendin oppositely to each other from the outer end.

6. A terminal connector comprising two members joined at one 'end and resilient means adapted to hold said members away from each other and a cylinder at the free end of each member, having its axis at right angles to the plane of movement of the memthe metal of which said members are com prised.
